基于InSAR数据分析四川盆地南部长宁页岩气区块地表形变场基本特征
Dizhen xuebao, 2022 近年来随着我国页岩气大规模开采，四川盆地南部活动构造相对稳定的地区出现了一系列微震和有感地震，甚至是破坏性地震。这些地震是否为工业开采所诱发，目前已有研究从时空相关性给出了一些统计推断，本文则从形变观测角度分析页岩气开采能否产生可以检测到的地面形变，以揭示形变信息与页岩气开采的关系，尝试为页岩气开采提供有效的监测手段。基于长波ALOS-2卫星雷达数据对长宁页岩气区块近两三年内的InSAR地表形变展开探测，检测页岩气大规模生产可能造成的地面形变及其基本特征，同时使用Sentinel ...

Dizhen xuebao渝东南武隆地区志留系龙马溪组页岩储层发育，构造裂缝是页岩气运移和聚集的主控因素，而古构造应力场控制着构造裂缝的发育，对武隆地区页岩气的勘探开发具有较大影响。本文对武隆地区及周缘发育的节理进行分期配套处理，明确了武隆地区的古构造应力方向，同时通过岩石声发射实验计算得到了古构造应力的大小。在此基础上，利用ANSYS有限元软件建立了武隆地区志留系龙马溪组地层关键构造变形期的地质模型，并通过构造应力场的分析结果明确了该地区关键构造期的构造应力特征，以确定构造应力场数值模拟的边界条件，进而对构造应力场进行数值模拟。
